The village of Endicott water department has advised those served by its system that pressure was lost around 12:30 a.m. Sunday.

The trouble was caused by a main line break on South Street. Some water customers in Endicott and in parts of Endwell lost pressure.

According to a statement issued Sunday morning by the department, when distribution pipes and mains lose pressure, it increases the chance that untreated water and harmful microbes could enter the system.

People who live in Endicott, as well as parts of Endwell, West Endicott and West Corners have been advised not to drink the water without boiling it first.

Water should be boiled for one minute and then cooled before it is used. Boiled or bottled water should be used for drinking, brushing teeth and food preparation until further notice.

The statement from the water department reported repair work on the main line was continuing.

A notice will be issued when the Endicott system's water is deemed to be safe.
